the emphasis here is on 'few' and must go 'right'. As the number of Critical success factors until they are successfully achieved.
Greene and loughridge further add that the identification of Critical success factors can help to clarify the nature and amount of resources that must be gathered to permit the development team to concentrate their efforts on meeting priority issues, rather than what the available technologies will allow. Evidently, these key areas of activity would need consistent and careful attention from top management if business intelligence system implementation and thus organization goals were to be attained. In other word, Critical success factors are high-level management consideration as distinet from a detailed set of project deliverable specifications. Hence, a set of Critical success factors for the development of any major information system, such as a Business intelligence system, is fundamentally different from the set of interlinked detailed tasks which must be accomplished satisfactorily to ensure a project's successful completion. Consequently,the success of Business intelligence system implementation may not be fully ensured by meeting the required Critical success factors, but failure to consider the Critical success factors will be a major constraint for the organization
Although Critical success factors were initially introduced to determine the information needs of executives, the approach has been extended to cover other areas of information system research. Despite the limited literature on entire Business intelligence system implementation issues, there exists a significant body of Critical success factors literature about the implementation of information systems, data warehouses, Enterprise resource planning systems and software projects. As a Business intelligence system is an enterprise-wide implementation effort similar to Enterprise resource planning systems and data warehouse, the adoption of a Critical success factors approach is therefore considered appropriate in this study of Business intelligence systems.
